Tips for maintaining efficiency in crushing circuits
Ideally, the reduction ratio of a jaw crusher should be 6:1. There are different ways to calculate reduction ratio, but the best way is something called the P80 factor. The reduction ratio is then calculated by comparing the input feed size passing 80 per cent versus the discharge size that passes 80 per cent. The finer the CSS, the greater the ...

Are Reduction Ratios Different Between Crushers?
Cone Crushers: Cone crushers are considered a secondary crusher. You shouldn't feed any material larger than 4" into one, but it can yield an 8 to 1 reduction. This means we can go down to ½" and even 3/8" depending on the feed size. Cone crushers are similar to jaw crushers in that they are relatively low wear. Impact Crushers:
